Summary

This episode details the harrowing true crime case of Denali Brehmer, who, after a childhood marked by extreme violence and subsequent struggles with addiction and prostitution, was catfished by an online predator named Darin Mitchell Schilmiller (posing as 'Tyler, the millionaire'). Schilmiller promised Denali $9 million to rape, torture, and murder a person and send him a video. Denali targeted her friend, Cynthia 'Cece' Hoffman, a young woman with a cognitive disability, exploiting her trust and vulnerability. Denali, along with several other teenagers, lured Cece to a remote location, bound her with duct tape under the pretense of a photo shoot, and then murdered her. The subsequent investigation heavily relied on advanced phone forensics, uncovering the entire plot, including Schilmiller's broader child exploitation activities and Denali's involvement in assaulting minor girls. The host, Boze, emphasizes the devastating impact of childhood trauma and society's failure to address it, while also highlighting Denali's ultimate accountability for her choices, a point underscored by her own sisters.
This case serves as a stark warning about the dangers of online manipulation and predation, particularly for vulnerable individuals. It illustrates how unaddressed childhood trauma can contribute to a cycle of violence and self-destruction, while also demonstrating that personal choices ultimately determine one's path.

Insights

1Denali Brehmer's Traumatic Childhood and Descent

Denali, originally Alexandria, grew up in a chaotic home in Anchorage, Alaska, where her mother's boyfriend inflicted daily violence, culminating in the death of her baby sister, Gabrielle, from abuse. Despite being adopted into a loving family who tried to give her a fresh start, her past trauma proved 'too powerful,' leading her to meth, heroin, prostitution, and eventually, drug distribution by age 16-17. An assault at 18 resulting in pregnancy further deepened her spiral.

Host details Alexandria's early life, the violence, Gabrielle's death, her adoption and name change to Denali, and her subsequent drug use, prostitution, and pregnancy from assault.

2The Catfishing and Murder-for-Hire Plot

Denali was catfished by Darin Mitchell Schilmiller, an 18-year-old from Indiana posing as 'Tyler, the millionaire,' who promised her $9 million for a video depicting the rape, torture, and murder of a chosen victim. Denali, vulnerable and addicted, believed the offer and recruited several other teenagers to assist in the plot.

Host describes 'Tyler' as a 'literal millionaire' who connected with Denali on Snapchat, the $9 million offer for a 'f*cked up video,' and the reveal of 'Tyler' as Darin Schilmiller, an unemployed teen in his grandparents' basement.

3Targeting of Cece Hoffman

Denali chose Cynthia 'Cece' Hoffman, a friend with a cognitive disability (functioning at a 12-year-old level), as her victim. Denali believed Cece would be easier to manipulate and also harbored resentment over a past conflict involving a boy they both liked.

Host details Cece's background, her learning disability, her sweet and vibrant nature, and Denali's reasoning for targeting her: trust, cognitive disability, and a past issue over a boy.

4Execution of the Murder and Cover-up

Denali and her accomplices lured Cece to Thunderbird Falls under the guise of a hike. They convinced Cece to be tied up with duct tape for 'pictures,' then shot her in the back of the head. Afterward, they attempted to cover their tracks by burning Cece's belongings and the weapon, and Denali sent a text to Cece's sister feigning concern for her whereabouts.

Host describes the drive to Thunderbird Falls, the binding of Cece with duct tape, Kayden Mintosh shooting Cece, and the burning of evidence.

5Role of Digital Forensics and Schilmiller's Broader Crimes

Advanced forensic technology on cell phones was pivotal in solving the case, recovering deleted messages and keystrokes that exposed the entire plot. This also revealed Schilmiller's extensive child exploitation activities, including soliciting videos of Denali assaulting minor girls (ages 8-15) and attempting to solicit images of infants from other young mothers across different states.

Host emphasizes the capabilities of 2019 forensic technology, the recovery of messages detailing the plot, and the discovery of Schilmiller's federal child porn charges and attempts to solicit content from other women.

6Sentences and Accountability

Denali Brehmer and Darin Schilmiller each received 99-year prison sentences for the murder, with additional charges. Kayden Mintosh, who pulled the trigger, received 70 years, and Caleb Leyland, who loaned the SUV, received 30 years. Schilmiller was designated a 'worst offender,' preventing parole for 45 years. Despite her traumatic past, Denali's own sisters asserted that her actions were a result of her choices, not merely her upbringing, as they experienced similar trauma but chose a different path.

Host details the sentences for Denali, Darin, Kayden, and Caleb, the 'worst offender' designation for Schilmiller, and the powerful statement from Denali's sisters.

Bottom Line

Adults often avoid directly addressing gruesome violence witnessed by children, leading to confusion and potential 'exploration' of violence later in life.

So What?

The host argues that this societal discomfort prevents children from processing trauma, potentially normalizing or mystifying violent events. Without emphatic clarification that such acts are abnormal and horrific, children may later seek to understand or replicate what they witnessed.

Impact

There is an opportunity for parents, educators, and mental health professionals to develop and implement direct, emotionally supportive communication strategies for children who witness violence, explicitly labeling the acts as wrong and the perpetrators as 'insane' to help children contextualize and reject such behavior.

Key Concepts

The Cycle of Unaddressed Trauma

The host posits that if children witness violence and adults fail to emphatically address it as abnormal and horrific, the children may become confused by violence and 'explore it later in life' in an attempt to understand it. This can lead to a perpetuation of violent behavior or a descent into dark paths.

Lessons

  • Educate yourself and others about the signs of online catfishing and manipulation, especially when large sums of money or illicit acts are involved.
  • Prioritize open and empathetic communication with children who witness traumatic or violent events, explicitly stating that the events were abnormal and wrong, to help them process and prevent future 'exploration' of violence.
  • Be vigilant about the online activities of vulnerable individuals, particularly those with cognitive disabilities or histories of trauma, as they may be targets for exploitation.
  • Support the development and use of advanced digital forensics in law enforcement to effectively investigate and prosecute complex online crimes and child exploitation cases.

Notable Moments

The host's personal rant about the need for doctors to implement online booking systems, despite Zocdoc's existence.

This moment provides a brief, relatable break from the heavy true crime narrative, showcasing the host's personality and injecting a touch of everyday frustration.

The detail about Cece Hoffman's father attending court with his emotional support Chihuahua, Bruiser, during his victim impact statement.

This specific, poignant detail powerfully humanizes the profound grief and trauma experienced by the victim's family, illustrating the deep emotional toll the crime took.

Denali's sisters, who shared her traumatic childhood, stating that Denali's actions were her own choices and not simply a product of their shared past.

This moment provides a critical counter-narrative to the idea that trauma solely dictates destiny, emphasizing individual agency and accountability even in the face of extreme adversity.

"If we don't talk about it, if we sit here and say, 'Oh, she was so normal,' then we don't understand why people commit these crimes."

Boze (Host)
"

"If you do not, a child will get so confused by violence that they will explore it later in life. They will try to understand that thing that they saw that nobody talked to them about and then they will explore it."

Boze (Host)
"

"Denali executed Cynthia Hoffman in a murder for higher plot. She conspired with numerous other individuals in and outside of Alaska, including juveniles, forever altering everybody's life. She may not have pulled the trigger, but this never would have happened if it were not for Denali Bremer."

District Attorney (quoted by Host)
"

"We don't understand why our sister did this. She made choices. She made those choices herself because we went through the same things and we would never and have never done anything like that."
